说明：  调频信号的时-频分析 针对时变信号有很好的效果(When FM signals- frequency analysis for time-varying signal has good results)

bayes分类器，脱机手写识别，含实验数据(bayes classifier, off-line handwriting recognition, with the experimental data)

非线性方程组的最速下降法，数值计算基于matlab的源程序。(Steepest descent method based on the Matlab nonlinear equations, numerical calculation)

这是一个实现256QAM星座映射的代码，使用格雷码编码方法。(This is an implementation of 256 qam constellation mapping code, the use of gray code encoding method. )

交错网格---非均匀介质二维声波方程(一阶压力--速度)、2阶时间差分、2阶空间差分精度(Staggered grid- heterogeneous medium two-dimensional acoustic wave equation (first-order pressure- speed), 2 order time difference, space 2 order difference accuracy)

激光雷达资料，包含星载激光多普勒测风雷达发展研究、星载激光雷达的发展与应用、激光雷达原理(Lidar data, including the development of laser Doppler wind radar spaceborne laser Doppler wind radar research,principle of lidar )

snake方法的主要局限性在于要求初始化要靠近期望的解和对边界的凹形部分的分割存在困难，GVF解决了这两个问题，并将其用于snake图像分割(The main limitation is the snake method requires initialization to be close to the desired solution and the boundary of the concave part of the division of the difficulty, GVF solve these two problems, and for the snake segmentation)

使用matlab来进行图像处理最经典的工具书，详细的介绍了图像处理的方法(Image processing using matlab to classic books, and a detailed description of the image processing method )
